Light-cone zero modes revisited
Thomas Heinzl
The vacuum problem of light-cone quantum field theory is reanalysed from a functional-integral point of view.
Observation of macroscopic Landau-Zener transitions in a superconducting device
A. Izmalkov, M. Grajcar, E. Il'ichev +7
A two-level system traversing a level anticrossing has a small probability to make a so-called Landau-Zener (LZ) transition between its energy bands, in deviation from simple adiab…
RV survey for planets of brown dwarfs and very low-mass stars in ChaI
Viki Joergens, Ralph Neuhäuser
We have carried out a radial velocity (RV) search for planets and brown dwarf companions to very young (1-10Myr) brown dwarfs and very low-mass stars in the ChaI star forming regio…
The van der Waals energy of atomic systems near absorbing and dispersing bodies
Stefan Yoshi Buhmann, Ho Trung Dung, Dirk-Gunnar Welsch
Within the frame of macroscopic quantum electrodynamics in causal media, the van der Waals interaction between an atomic system and an arbitrary arrangement of dispersing and absor…
Low-frequency measurement of the tunneling amplitude in a flux qubit
M. Grajcar, A. Izmalkov, E. Il'ichev +13
We have observed signatures of resonant tunneling in an Al three-junction qubit, inductively coupled to a Nb LC tank circuit. The resonant properties of the tank oscillator are sen…
